Hello Afro Man,
The compass needle (or card) needs to be 'balanced' to suit the Northern or Southern Hemisphere. You are right they all point to Magetic North, but if I take my compass too far north of the equator the needle (or card) is going to be out of balance and drag along the compass housing. To complicate it a little more, some specialised compasses like the Silva Expedition models are balanced for magnetic zones within the hemispheres.
